DESCRIPTION
RUR
Transmit - Discard Cell Count - Byte 3[7:0]:
This RESET-upon-READ register, along with the "Transmit ATM Cell
Processor Block - Transmit ATM Cell Discard Cell Count - Bytes 2
through 0" registers, contain a 32-bit value for the number of ATM cells
that have been discarded by the Transmit ATM Cell Processor block.
This particular register contains the MSB (Most Significant Byte) value
of this 32-bit expression.
NOTES:
1. The contents within these register includes all ATM cells that
contain either a HEC Byte error or a "Transmit UTOPIA
Parity" error.
2. If the number of Cells reaches the value "0xFFFFFFFFF"
then these registers will saturate to and remain at this value
(e.g., it will NOT overflow to "0x00000000").
